在第一个 运行 和试用期结束后显示应用程序注册对话框
Show application Registration dialog on first run and after trial expired
我正在使用这个库创建一个实现试用期的 WPF 应用程序 Application Trial Maker 这个库在 SystemFile 上编写注册数据但是当我在我的项目中实现它时，它会在每个申请 运行.
我想要的是仅在两种情况下显示注册对话框：
1- 首先 运行：在用户设置我的应用程序之后。我发现这 2 个问题 and show dialog on first start of application 两个问题的答案都使用 Application.Setting 并在那里添加了一个 bool 变量，但就我而言，我想利用我的 Trial Maker 库我也不能在我的 main 中使用 Setting.Default[] 因为它是 non-static 并且我没有调用特定的视图模型。我只是打电话给 App.Run，您将在下面看到。
2- 当试用期或 运行s 到期时。

我已经为 TrialPeriodRuns 添加了 getter 以便使用它。
在其他情况下，我希望我的应用程序直接 运行 而无需注册对话框。其他情况是当它是完整版时或者当它是未过期的试用版而不是第一次 运行ning 时。
有什么想法可以实现吗？？
我建议您在 Windows 注册表中写入必要的数据。
您可以使用此参考：https://msdn.microsoft.com/en-us/library/h5e7chcf.aspx
感谢与@Akram Mashni 的上述讨论。我想出了这个解决方案，它适用于我的场景。
我将 DaysToEnd() 方法修改为 public，这样我就可以从其他任何地方使用 TrialMaker class 的实例调用它（例如我的 Main()）：
public int DaysToEnd()
{
FileInfo hf = new FileInfo(_HideFilePath);
if (hf.Exists == false)
{
MakeHideFile();
return _DefDays;
}
return CheckHideFile();
}
然后我在 Main() 方法中使用它来检查我的场景。当我调用 DaysToEnd() 时，它将通过在其中调用 CheckHideFile() 来更新存储在 SystemFile 上的信息。
我先打电话给 DaysToEnd()，这样我就可以更新 SystemFile
中的信息
DaysToEnd() 将 return int 代表试用期剩余天数的值。我还为我之前添加到库中的 TrialPeriodRuns 调用了 get，它代表试用期内的剩余运行。
我还实现了嵌套的 if-else 语句来检查我的场景：
int daystoend = t.DaysToEnd();
int trialperiodruns = t.TrialPeriodRuns;
/// Check if it is first run here
if (dte == 15 && tpr == 1000)
{
bool is_trial;
/// then show the Registration dialog
TrialMaker.RunTypes RT = t.ShowDialog();
if (RT != TrialMaker.RunTypes.Expired)
{
if (RT == TrialMaker.RunTypes.Full)
is_trial = false;
else
is_trial = true;
PharmacyManagementSystem.App app = new PharmacyManagementSystem.App();
app.InitializeComponent();
app.Run();
}
}
/// Check if it is trial but not first run
/// no Registration Dialog will show in this case
else if (dte > 0 && tpr > 0)
{
PharmacyManagementSystem.App app = new PharmacyManagementSystem.App();
app.InitializeComponent();
app.Run();
}
/// Check if it is expired trial
else if (dte == 0 || tpr == 0)
{
bool is_trial;
/// then show the Registration Dialog here
TrialMaker.RunTypes RT = t.ShowDialog();
if (RT != TrialMaker.RunTypes.Expired)
{
if (RT == TrialMaker.RunTypes.Full)
is_trial = false;
else
is_trial = true;
PharmacyManagementSystem.App app = new PharmacyManagementSystem.App();
app.InitializeComponent();
app.Run();
}
}
/// the full version scenario remain and it comes here
/// no need to show Registration Dialog
else
{
bool is_trial;
TrialMaker.RunTypes RT = t.ShowDialog();
if (RT != TrialMaker.RunTypes.Expired)
{
if (RT == TrialMaker.RunTypes.Full)
is_trial = false;
else
is_trial = true;
PharmacyManagementSystem.App app = new PharmacyManagementSystem.App();
app.InitializeComponent();
app.Run();
}
}
最后它对我来说就像一个魅力
